PREFACE. 

The  purpose  of  this  catalogue  is  to  record  Jbe;results  of  \aiiJ  examina- 
tion of  a  portion  of  the  bottom  material  obtkmed' during  the  dredgiug 
operations  of  the  U.  S.  Fish  Commission  sf earner;  Albwifo'$s,'' pnil  at  tlie 
same  time  to  furnish  a  convenient  book  of  Reference  for  those  who  are, 
or  may  become,  sufficiently  interested  to  continue  the  study  of  this 
material. 

The  examination,  while  very  far  from  exhaustive,  has  been  pursued 
with  greater  or  less  diligence,  as  time  and  opportunity  offered,  for  sev- 
eral years.  Material  from  about  one  hundred  and  twenty-five  stations 
has  been  carefully  studied,  and  specimens  from  more  than  a  hundred 
localities  have  been  preserved  and  identified.  Of  these  localities, 
fifty-eight  are  in  the  North  Atlantic  Ocean,  twenty-one  in  the  Gulf  of 
Mexico,  seven  in  the  Caribbean  Sea,  one  in  the  South  Pacific,  and 
five  in  the  North  Pacific.  The  depths  at  these  stations  vary  from  7  to 
2,512  fathoms. 

The  figures  in  illustration  are  from  photographs  of  mounted  speci- 
mens on  exhibition  in  the  U.  S.  National  Museum,  Division  of  Marine 
Invertebrates.  A  uniform  enlargement  of  about  15  diameters  has 
been  maintained  in  the  figures,  sometimes  at  a  sacrifice  of  detail  in 
the  smaller  specimens  which  would  have  been  made  clearer  by  the  use 
of  a  higher  magnifying  power,  but  for  the  purpose  of  identification  it 
is  believed  to  be  more  useful  to  mark  distinctly  the  relative  size  of  the 
objects.  The  exhibition  series  has  been  mounted  expressly  for  public 
display.  The  individuals  of  each  species  are  attached  in  various  atti- 
tudes to  the  bottom  of  the  shallow  cavity  of  a  concave,  blackened  disk 
of  brass.  For  security  each  disk  is  provided  with  a  removable  fenes- 
trated  brass  cap  having  a  top  of  thin  glass.  These  disks  are  arranged 
in  concentric  rows  upon  a  large  circular  metal  plate  which  occupies 
the  place  of  the  stage  of  an  ordinary  microscope.  The  circular  plate 
is  given  both  a  rotary  and  a  to-and-fro  movement  by  means  of  a  fric-

tion  roller  and  a  rack  and  pinion,  so  that  all  the  mounts  may  be  suc- 
cessively brought  under  the  microscope.  The  specimens  thus  arranged 
are  inclosed  in  a  box  having  a  glass  top,  through  which  the  objective 
of  a  microscope  projects.1 

In  the  following  catalogue  the  classification  of  Mr.  H.  B.  Brady  has 
been  followed,  as  presented  in  "  The  report  on  the  Foraminifera  col- 
lected by  H.  M.  S.  Challenger,"  and  his  definitions  of  families  and 
genera  have  been  appropriated  bodily.  The  analytical  table  is  also 
compiled  chiefly  from  the  above-mentioned  report.  The  descriptions 
of  species  have  been  prepared  after  study  of  the  reserve  series  as  well 
as  of  the  typical  specimens  reproduced  in  the  illustrations. 

The  localities  given  are  only  those  from  which  specimens  have  been 
taken  in  selecting  the  series  exhibited  and  in  reserve,  and  do  not 
profess  to  represent  the  distribution  of  the  species. 

A  supplementary  table  gives  the  latitude,  longitude,  and  depth  of 
water  of  the  stations  referred  to  in  the  catalogue. 

THF.  FORAMINIFERA. 


The  Foraoninifrra  are  minute  aquatic,  mostly  marine,  animals,  having 
semifluid  bodies,  composM  -jf. granular  protoplasm,  inclosed  in  shells 
or  "tests"  either  secreted  by  the  animal  or  built  up  of  available  foreign 
material,  such  as  mud,  sand,  sponge  spicules,  or  dead  shells.  In  zoologi- 
cal classification  they  belong  to  the  Ixhizopod  group  of  the  Protozoa, 
and  are  distinguished  from  other  members  of  the  group  by  the  single 
character  of  the  reticulated  form  assumed  by  their  pseudopodia  when 
extended. 

These  minute  animals  are  interesting  objects  of  study,  geologically 
and  biologically  as  well  as  esthetically.  As  objects  of  beauty  they 
arrest  the  attention  of  even  the  casual  observer  by  the  delicacy  of 
their  structure  as  well  as  the  symmetry  and  variety  of  their  forms. 
Geologically  they  are  of  interest  because  they  are  among  the  most 
ancient  and  abundant  of  fossils  and  also  the  most  efficient  of  rock 
builders.  Biologically  they  are  instructive  examples  of  the  powers  and 
possibilities  of  an  individualized  bit  of  protoplasm — "a  little  particle 
of  apparently  homogeneous  jelly,  changing  itself  into  a  greater  variety 
of  forms  than  the  fabled  Proteus,  laying  hold  of  its  food  without  mem- 
bers, swallowing  it  without  a  mouth,  digesting  it  without  a  stomach, 
appropriating  its  nutritious  material  without  absorbent  vessels  or  a 
circulating  system,  moving  from  place  to  place  without  muscles,  feeling 
(if  it  has  any  power  to  do  so)  without  nerves,  propagating  itself  without 
genital  apparatus,  and  not  only  this,  but  forming  shelly  coverings  of  a

It  has  been  subjected  to  the  very  severe  test  of  years  of  use  by  the  general  public, 
children  as  well  as  adults,  to  the  number  of  hundreds  each  day/ and  this  with  only 
the  occasional  presence  of  an  attendant  in  the  room.  See  Eeport  U.  S.  Nat.  Mas.,

symmetry  and  complexity  not  surpassed  by  those  of  any  testaceous 
animals."1 

From  the  resemblance  of  some  of  the  shells  of  the  foramiuifera  to 
those  of  the  nautilus,  they  were  for  a  long  time  regarded  as  minute 
cephalopod  mollusks;  that  is,  among  the  highest  of  the  invertebrates, 
and  it  was  not  until  the  year  1835  that  their  true  nature  was  discovered 
and  announced  by  M.  Dujardin  to  the  French  Academy  of  Sciences. 
Since  that  time  the  study  of  this  order  of  animals  has  been  pursued  by 
able  naturalists,  and  the  results  of  their  investigations  appear  in  a 
voluminous  literature.  Much  yet  remains  to  be  learned  of  the  life  his- 
tory of  the  animal,  but  its  zoological  position  is  established  and  its 
importance  in  the  economy  of  nature  recognized. 

As  fossils  the  foraminifera  are  common  in  all  geological  systems  from 
the  Devonian  upward,  but  they  are  especially  abundant  in  Mesozoic  and 
Cenozoic  time.  The  chalk  and  many  of  the  most  extensive  limestone 
beds  are  formed  principally  of  their  remains.  As  to  present  habitat, 
their  shells  are  found  wherever  dredgings  are  made,  all  over  the  ocean 
floor  except  in  the  polar  regions.  A  few  species  are  "pelagic;"  that  is, 
they  are  found  living  at  or  near  the  surface  of  the  water,  but  the  weight 
of  evidence  is  in  favor  of  the  conclusion  that  the  vast  majority  of  them 
pass  all  stages  of  life  at  the  bottom,  where  they  are  found.  In  the 
experience  of  the  naturalists  of  the  Albatross  it  was  rare  to  find  any 
but  the  most  minute  and  thin-shelled  forms  in  the  surface  dredgings, 
and  still  more  rare  for  any  to  be  taken  in  the  "wing  nets"  that  were 
usually  attached  to  the  dredging  apparatus. 

The  living  foraminifer  is  a  minute  bit  of  viscid,  granular  protoplasm, 
without  organs  or  tissues,  without  differentiation  of  substance  into  outer 
membrane  and  inner  contents,  and  in  most  instances  without  evident 
nucleus  or  contractile  vesicle.  A  nucleus  has  been  recognized  in  a  few 
individuals,  and  hence  this  characteristic  element  of  most  living  cells 
is  inferred  to  be  present  in  all  the  members  of  the  order.  Like  other 
Rhizopods,  it  has  the  power  to  protrude  any  parts  of  its  body  as  "pseu- 
dopodia," for  the  purpose  of  locomotion  or  the  prehension  and  absorption 
of  food.  It  differs,  however,  from  the  other  Khizopods  in  that  the 
pseudopodia  do  not  necessarily  remain  distinct,  but  flow  together  when- 
ever they  touch  one  another,  forming  sometimes  an  elaborate  and 
extended  network  of  protoplasmic  threads,  which,  however,  may  be 
readily  retracted  and  flow  again  into  the  body  mass,  leaving  no  indica- 
tion of  their  previous  existence. 

How  the  function  of  nutrition  is  accomplished  and  the  nature  and 
condition  of  the  organic  material  used  as  food  by  these  minute  animals 
is  not  yet  determined.  Without  doubt  the  pseudopodia  are  capable  of 
seizing  and  inclosing  small  organic  particles  with  which  they  may  come 
in  contact,  and  any  part  of  the  protoplasmic  body,  of  which  the  pseudo- 
podia are  but  temporary  extensions,  is  able  to  digest  and  assimilate  the

nutritive  portion.  To  furth'er  account  for  the  necessary  food  supply,  it 
is  believed  that  the  Foraminifera  absorb  organic  matter  held  in  solu- 
tion by  the  sea  water.  This  theory  is  the  more  easily  accepted  since 
we  know  that  they  have  the  power  to  separate  inorganic  matter  (car- 
bonate of  lime  in  particular)  from  its  solution,  with  which  to  construct, 
wholly  or  in  part,  their  shells. 

Of  the  process  of  reproduction  little  is  known  beyond  the  fact  of 
multiplication  by  gemination  and  fission.  Every  part  of  this  simple 
animal  being  sufficient  unto  itself  for  purposes  of  nutrition  and  growth, 
it  follows  that  a  fragment  of  the  protoplasmic  body  cast  off  from  the 
parent  becomes  at  once  a  new  individual  and  the  possible  founder  of  a 
fresh  colony.  But  it  is  not  in  accord  with  what  we  know  of  the  life 
histories  of  other  living  things  that  this  process  of  subdivision  or  prop- 
agation by  cuttings  or  shoots  can  go  on  indefinitely.  It  is  more  likely 
that  some  kind  of  sexual  reproduction  takes  place,  the  manner  of  which 
is  yet  to  be  demonstrated. 

The  most  striking  characteristic  of  this  simple,  semifluid  animal,  of 
indefinite  and  changeable  shape,  is  its  ability  to  construct  a  shell  or 
test  of  definite  form  in  which  to  shelter  itself.  This  shell  or  test  may 
be  irregular,  simple,  and  rude  in  construction,  or  symmetrical  and  of 
great  delicacy  and  beauty,  in  variety  of  forms  rivaling  the  shells  of  the 
Mollusca,  of  which  it  was  long  thought  to  be  a  diminutive  example. 

Structurally  there  are  three  quite  definite  and  distinct  types  of  tes- 
taceous covering.  The  first,  to  begin  with  the  lowest  and  least  common, 
is  the  "chitinous"  test — a  thin,  transparent,  yellowish  or  brownish 
membranous  investment  secreted  by  the  animal.  It  has  one  or  more 
general  apertures,  but  is  not  perforated  with  fine  foramina,  and  there 
is  no  means  of  communication  between  the  inside  and  outside  of  the 
test  except  by  the  general  apertures.  The  foraminifera  with  this  kind 
of  shell  have  been  grouped  in  the  single  family  of  Gromidce.  As  a  rule 
they  inhabit  only  fresh  or  brackish  water.  They  have  not  been  found 
in  deep-water  marine  collections,  and  do  not  appear  in  the  following 
catalogue. 

The  second  type  is  the  so-called  "arenaceous"  test.  This  is  an 
investment  constructed  of  grains  of  sand,  or  of  the  dead  shells  of  other 
foraminifera,  or  of  sponge  spicules,  or  even  of  mud,  cemented  together 
more  or  less  firmly  by  means  of  a  calcareous  cement  secreted  by  the 
animal.  Usually  it  has  one  or  more  general  apertures  of  comparatively 
large  size,  and  in  addition  there  may  be  minute  orifices  between  the 
sand  grains,  or  other  substances  of  which  the  test  is  constructed, 
through  which  the  delicate  threads  of  protoplasm  can  be  projected. 
The  surfaces  may  be  rough  and  coarse  or  smooth  and  highly  finished, 
according  to  the  fineness  of  the  material  used  and  the  amount  of  cement 
deposited  in  the  crevices  and  angles  between  the  grains.  When  con- 
structed of  mad  these  tests  are  found,  in  some  instances,  to  have  a 
chitiuous  base,  which  maintains  the  shape  of  the  investment. 


DESCRIPTIVE    CATALOGUE    OF    RECENT    FORAMINIFERA.       255 

The  third  type  of  structure  is  a  true  shell,  composed  almost  entirely 
of  carbonates  of  lime  and  magnesia  separated  by  the  animal  from  their 
solution  in  the  sea  water,  and  fixed  in  solid  form.  It  is  through  the 
agency  of  the  foraminifera  principally  that  the  limestone,  which  is  con- 
stantly being  dissolved  by  rains  and  carried  by  rivers  to  the  sea,  is 
restored  to  the  solid  crust  of  the  earth.  Of  these  "calcareous"  shells 
there  are  two  kinds,  quite  distinct  in  appearance,  known  as  "porcel- 
lanous"  and  "  hyaline."  The  former  are  usually  white,  opaque,  shining 
with  the  peculiar  luster  of  porcelain,  and  "imperf  orate;"  the  latter  arc 
transparent,  glassy,  and  "perforate,"  more  or  less  densely,  by  minute, 
parallel,  unbranched  tubes  for  the  passage  of  delicate  pseudopodia.  In 
both  kinds  there  are  usually  one  or  more  comparatively  large,  general 
apertures.  Surface  marking,  or  "ornamentation,"  is  common  in  both 
the  porcellanous  and  hyaline  shells.  In  the  former  they  take  the  form 
of  striatious  or  pittings,  more  or  less  regular  and  conspicuous;  in  the 
latter,  of  ridges,  tubercles,  or  spines,  of  clear  nontubular  shell-substance, 
varying  constantly  in  number  and  prominence  among  individuals  of  the 
same  species. 

Architecturally  the  first  and  most  obvious  division  of  these  shells  is 
into  single-chambered  (inonothalamous,  or  unilocular)  and  many-cham- 
bered (polythalamous,  or  rnultilocular).  While  the  primitive  form  of 
both  the  single  and  many  chambered  shells  is  evidently  globular,  yet 
the  possibilities  of  ultimate  conformation,  depending  chiefly  upon  direc- 
tion of  growth,  are  very  great.  Thus  a  mouothalamous  shell,  beginning 
as  an  incomplete  spherical  chamber,  may  become  ovate,  flask-shaped, 
spindle  shaped,  star-shaped,  or  tubular,  and  the  tubular  form  may  be 
straight,  curved,  coiled,  or  quite  irregular.  And  these  forms  pass  from 
one  into  another  by  quite  insensible  degrees.  The  polythalamous  shell 
is  a  consequence  of  the  process  of  reproduction  by  "gemmation,"  as 
the  other  is  of  reproduction  by  "fission."  In  this  case  the  growing 
sarcode  pushes  outside  the  initial  chamber  until  at  a  certain  stage  it 
builds  a  new  wall  around  itself,  while  still  maintaining  connection  with 
the  parent  cell.  This  second  segment  may  give  origin  to  a  third,  and 
so  on  until  a  colony  is  established,  each  offspring  occupying  an  apart- 
ment added  to  the  parental  home.  It  is  easy  to  see  that  the  style  of 
architecture  of  these  tenements  may  be  almost  infinitely  varied  by  vary- 
ing the  shape  and  position  of  these  annexes.  Each  annex  may  have 
any  of  the  forms  of  the  mouothalamous  shells  or  any  modification  of 
them,  and  the  arrangement  may  be  in  straight  or  curved  lines,  in  con- 
centric circles  or  planospiral  coils,  in  single  or  double  series  spirally 
coiled,  in  two  or  three  alternating  series  not  spiral,  or  even  in  an  irreg- 
ular and  disorderly  mass. 

Usually  in  the  development  of  the  polythalamous  'shell  each  succes- 
sive segment  uses  the  party  walls  of  the  preceding  segments,  so  far  as 
they  may  be  available,  in  the  construction  of  its  own  annex,  but  in 
some  of  the  higher  types  of  the  hyaline  series  it  will  be  found  that 


256  REPORT    OF    NATIONAL    MUSEUM,   1897. 

each  chamber  has  a  complete  wall  of  its  own,  thus  making  double  par- 
titions between  them.  In  some  of  these  higher  types  there  is  devel- 
oped also  what  is  called  a  "  supplemental  skeleton,"  which  consists  of 
a  deposit  of  shell-substance  on  the  outside  of  the  original  wall,  thereby 
adding  to  its  thickness,  filling  in  the  hollows  between  the  segments  and 
at  the  umbilici,  and  sometimes  growing  out  into  protuberances  of 
various  shapes.  This  supplemental  skeleton  is  generally  traversed  by 
a  set  of  canals  or  sinuses — passages  left  during  the  deposit  of  the 
shell-substance,  and  probably  occupied  by  threads  of  sarcode  during 
the  life  of  the  animal. 

The  separation  into  families,  genera,  and  species  of  a  group  of  ani- 
mals like  the  foraminifera,  where  variation  is  the  rule  and  passage  from 
one  type  to  another  is  by  a  sliding  scale  and  not  even  by  a  series  of 
steps,  is  extremely  difficult,  and  must  always  remain  unsatisfactory  in 
some  particulars;  but  for  convenience  of  reference,  if  for  no  other 
reason,  a  classification  of  some  sort  is  demanded,  and  various  schemes, 
which  it  is  unnecessary  here  to  enumerate,  have  been  put  forth  to  bridge 
the  difficulty.  In  all  these  schemes  the  primary  divisions  are  founded 
upon  the  structure  of  the  test  as  above  described — that  is,  whether 
chitinous,  arenaceous,  or  calcareous,  and  whether  perforate  or  imperfo- 
rate.  Beyond  these  distinctions,  which  seem  to  have  a  physiological 
foundation,  there  is  nothing  upon  which  to  base  a  classification  but  the 
form  of  the  test,  which,  as  we  have  seen,  is  never  determinate  enough 
to  permit  of  the  establishment  of  fixed  boundary  lines.  Generic  and 
specific  names  of  foraminifera,  therefore,  must  not  be  considered  as 
having  much  zoological  value,  but  only  as  convenient  titles  applied  to 
certain  typical  forms  around  which  many  varieties  may  be  grouped. 
And  it  must  be  remembered  that,  however  elastic  the  definitions  of 
species,  or  even  genera,  there  will  often  be  a  margin  of  doubt,  and 
the  determination  of  place  in  the  classification  must  be  left  to  the 
preference  of  the  individual  observer. 

A  few  words  concerning  the  manipulation  of  material  and  specimens 
may  be  of  assistance  to  those  beginning  the  study  of  the  foraminifera. 

Collection  of  recent  shallow- water  forms  may  be  made  from  shore 
sands,  from  the  anchor  and  chains,  and  especially  from  the  "  chain 
lockers  "  of  ships,  from  sponge  sand,  and  by  means  of  boat  dredges  from 
the  shallow  waters  of  the  coast.  Deep-water  forms  are  only  obtain  able 
by  special  apparatus,  such  as  is  used  in  deep  sea  sounding  or  in  purely 
scientific  explorations  of  the  ocean  bed.  The  specimens  may  be  freed 
from  mud  by  the  process  of  decantation — that  is,  repeatedly  agitating 
in  water,  and,  after  a  very  brief  period  to  allow  subsidence  of  the  shells, 
pouring  oif  the  turbid  surface  water.  Or  the  material  may  be  put  in  a 
bag  made  of  fine  bolting  cloth  and  the  bag  shaken  in  a  bucket  of  water. 
The  remaining  foraminifera,  mixed  with  more  or  less  sand,  pteropod 
shells,  sponge  spicules,  and  debris  of  various  sorts,  should  then  be 
thoroughly  dried,  bottled,  and  labeled. 

For  examination  of  the  dried  material  a  dissecting  microscope  stand, 


DESCRIPTIVE    CATALOGUE    OF    RECENT    FORAMINIFERA.       257 

with  a  good  ticromatic  lens  magnifying  about  10  diameters,  is  most 
convenient.  A  small  quantity  of  the  material  in  a  shallow  watch  glass 
blackened  on  the  under  side,  being  placed  under  the  lens,  is  carefully 
inspected,  and  when  a  specimen  is  found  which  it  is  desired  to  pre- 
serve it  may  be  readily  removed  by  means  of  a  very  fine  camel's  hair 
pencil  slightly  moistened  between  the  lips.  Transfer  of  specimens 
should  be  attempted  with  the  moistened  pencil  only,  as  the  use  of  forceps 
is  certain  to  crush  the  delicate  shells. 

For  preservation  of  the  identified  specimens  in  numbers  for  study 
nothing  is  better  than  wooden  slides  of  regulation  size — 1  by  3  inches. 
These  may  have  either  a  concavity  drilled  in  one  side  nearly  through 
the  wood  and  painted  black,  or  a  hole  bored  entirely  through  the  slide 
and  one  side  covered  with  heavy  blackened  paper.  A  removable  cover 
to  this  little  cavity  may  be  cut  from  a  thin  sheet  of  mica  and  held  in 
place  either  by  a  spring  clamp  or  by  slipping  it  under  the  thin  paper 
front  of  the  slide,  which  is  left  uuglued  about  the  center  for  that 
purpose. 

To  make  a  section  the  specimen  should  be  attached  in  the  desired 
attitude  to  the  face  and  near  the  end  of  a  glass  slip  by  means  of  the 
minutest  drop  of  liquid  glue.  The  attitude  of  the  specimen  must  be 
carefully  preserved  until  the  glue  has  set.  The  shell  is  then  covered 
with  chloroform  or  xylol  balsam,  which  may  be  made  to  penetrate  the 
chambers  of  the  shell  and  be  rapidly  hardened  by  the  application  of 
direct  heat  up  to  the  boiling  temperatnre.  Superfluous  balsam  being- 
cut  away,  the  shell  supported  by  the  balsam  is  rubbed  lightly  upon  a 
hone,  kept  thoroughly  wet  with  water,  until  the  desired  section  is 
exposed.  The  balsam  is  then  dissolved  away  by  chloroform,  and  the 
glue  by  water,  and  the  specimen  mounted. 

The  manner  in  which  specimens  shall  be  mounted  will  depend  upon 
the  preferences  or  ingenuity  of  the  preparator,  and  the  arrangements  he 
may  make  for  the  storage  of  his  collection.  If  a  cover-glass  is  used  it 
should  not  be  sealed  on,  as  the  underside  of  the  glass  is  almost  certain 
to  "sweat"  sooner  or  later,  and  obscure  the  specimen.  It  may  be  worth 
while  to  say  that  for  the  attachment  of  the  shells  to  any  surface  the 
author  has  not  found  anything  better  than  microscopists'  gold  size. 
The  best  instrument  for  transferring  the  minute  drop  of  adhesive 
material  of  Avhatever  kind  to  the  point  where  the  shell  is  to  be  attached 
is  the  finest  obtainable  sewing  needle,  the  eye  end  inserted  in  a  slender 
handle  and  the  point  broken  off  at  the  thickest  part  of  the  needle. 

The  literature  of  the  subject  is  very  large,  though  most  of  it  is  to  be 
found  in  journals  of  natural  history  and  transactions  of  societies.  With 
Carpenter's  "Introduction  to  the  Study  of  the  Foraminifera,"  Brady's 
"Beport  on  the  Foraminifera  collected  by  H.  M.  S.  Challenger"  and 
Sherborn's  "Index  to  the  Genera  and  Species  of  the  Foraminifera,"  the 
student  will  be  able  to  begin  work  in  an  intelligent  manner  and  to  find 
references  to  all  that  has  been  published  on  this  subject  up  to  the  most 
recent  date.

Cylindrical  or  slightly  tapering;  triserial  portion  very  short;  nodo- 
sarian  segments  usually  three  or  four  in  number,  clearly  denned  by 
depressed  sutures;  walls  coarsely  arenaceous,  rough;  chambers  par- 
tially divided  by  a  network  of  incomplete  septa  springing  from  the 
outer  wall;  aperture  a  simple  rounded  orifice  in  a  central  slight  depres- 
sion at  the  end  of  the  final  segment.  Section  shows  the  apparent 
thickness  of  the  walls  due  to  the  cancellar  structure,  and  the  form  of 
the  chambers.  Length,  about  1.5  mm.  (-^  inch).

CLAVULINA   PARISIENSIS    d'Orbigny. 
(Plate  35,  fig.  2.) 

The  distinguishing  characteristic  of  this  species  is  the  triangular 
contour  of  the  triserial  portion  of  the  test;  otherwise  it  strongly  resem- 
bles C.  communis.  It  is  somewhat  coarser  and  rougher  than  the  latter, 
and  near  the  oral  end  the  sutures  are  often  much  depressed.

CLAVULINA    PARISIENSIS,  variety    HUMILIS    Brady. 
(Plate  36,  fig.  1.) 

The  variation  consists  in  its  smaller  size,  rougher  exterior,  the  deep 
depression  of  the  sutures,  often  forming  a  distinct  neck  between  the 
two  last  segments,  and  the  aperture  borne  at  the  end  of  a  long  tubular 
prolongation  of  the  final  segment. 

Localities.— Gulf  of  Mexico,  and  off  the  coast  of  Brazil  (stations 
2377,  2399,  2400,  2762),  59  to  210  fathoms.

(Plate  36,  fig.  2.) 

Arrangement  of  segments  as  in  other  species  of  Clavulina,  triserial 
at  first,  then  uniserial  and  rectilinear.  Differs  from  the  other  species 
in  the  triangular  contour  of  transverse  section  of  the  uniserial  as  well 
as  the  triserial  portion  of  the  test;  aperture  a  central  arched  slit  with 
a  protruding  lower  lip.

(Plate  39,  fig.  2.) 

A  stout,  inflated,  smooth,  and  polished  shell,  slightly  compressed 
from  above  downward,  nearly  circular  in  outline  when  seen  from  above, 
the  final  segment  projecting  well  beyond  the  preceding  one,  to  which  it 
is  smoothly  and  firmly  joined;  aperture  usually  a  broad  slit  with  a 
nearly  equally  broad  valvular  lower  lip.  Diameter,  1.5  mm.  (-fa  inch), 
more  or  less.  Longitudinal  section  shows  arrangement  of  chambers 
characteristic  of  the  genus,  and  the  apertures  alternately  at  opposite 
ends  of  the  shell. 

Localities. — Off  Cape  Hatteras  and  in  the  Gulf  of  Mexico  (stations 
2115,  2352,  2385),  460  to  840  fathoms. 

BILOCULINA  COMATA  Brady. 
(Plate  39,  fig.  3.) 

Subglobular  in  form,  otherwise  like  B.  ringens ;  characterized  specific- 
ally by  surface  ornamentation  consisting  of  more  or  less  conspicuous, 
fine,  straight,  parallel  stria3  covering  the  whole  shell;  aperture  an 
arched  slit,  with  a  broad,  thick  valvular  lower  .lip. 

Locality. — West  coast  of  Cuba  (station  2352),  463  fathoms. 

BILOCULINA  ELONGATA  d'Orbigny. 
(Plate  39,  fig.  4. ) 

Like  B.  ringens  except  that  it  is  long  oval  in  contour.  The  typical 
specimens  are  small,  but  there  is  constant  variation  both  in  size  and 
breadth  of  oval. 

Localities. — Gulf  of  Mexico  and  the  North  Atlantic  (stations  2383, 
2385,  2584),  500  to  1,200  fathoms. 

BILOCULINA  DEPRESSA  d'Orbigny. 
(Plate  40,  fig.  1.) 

Smooth,  compressed,  round;  margin  thin  and  sharp:  aperture  usu- 
ally a  long,  narrow  slit,  with  a  valvular  lower  lip  thinner  and  less 
prominent  than  in  B.  ringens  ;  rarely  the  aperture  is  contracted  to  a 
nearly  circular  orifice.  Longitudinal  section  shows  the  conformation 
and  arrangement  of  the  chambers. 

Localities. — Gulf  of  Mexico  and  off  Marthas  Vineyard  (stations  2374,

BILOCULINA  DEHISCENS,  new  species. 
(Plate  40,  fig.  3.) 

This  species  has  the  same  general  characters  as  B.  depressa  and  its 
variety  serrata,  but  the  last  two  chambers  are  more  or  less  separated  at 
the  sides,  giving  the  shell  the  appearance  of  rupture  from  internal 
growth  and  distension.  In  general  the  separation  is  sufficient  to  show 
the  sharp  edge  of  the  third  segment  on  each  side,  but  series  presenting 
all  degrees  of  gradation  from  Biloculina  to  Spiroloculina  have  been 
selected  from  material  dredged  at  a  single  station. 

Locality. — Gulf  of  Mexico  (station  2377),  210  fathoms.  (See  Spiro- 
loculina robusta,  series.) 

BILOCULINA  L^VIS  Defrance. 

(Plate  41,  fig.  1.) 

Less  compressed  than  B.  depressa,  less  inflated  than  B.  ringens ; 
characterized  by  the  double  border  formed  by  the  slight  projection  of 
the  margin  of  the  penultimate  segment. 

Locality.— Gulf  of  Mexico  (station  2394),  420  fathoms. 

BILOCULINA  SPH.ERA  d'Orbigny. 
(Plate  41,  fig.  2.)

chamber  incloses  the  preceding  one  almost  entirely,  leaving  exposed 
only  a  small  circular  segment  of  the  penultimate  chamber.  Aperture 
an  irregular,  often  branched  or  bordered,  V-shaped  slit.  Section  shows 
arrangement  of  chambers  and  degree  of  investment. 

Localities. — North  Atlantic,  Gulf  of  Mexico,  and  coast  of  Brazil  (sta- 
tions 2352,  2385,  2415,  2754,  2760),  440  to  1,000  fathoms. 

BILOCULINA  IRREGULARIS  d'Orbigny. 

(Plate  41,  fig.  3.) 

Differs  from  other  species  of  this  genus  in  that  it  is  compressed  at 
the  sides  instead  of  from  above  downward.  Seen  from  above  the  con- 
tour is  oval;  from  the  side  the  outline  is  broader,  approaching  the 
circular  when  the  compression  is  considerable.  Aperture  circular  or 
broad,  with  a  valvular  lip  in  the  somewhat  protuberant  oral  end. 

Localities. — Caribbean  Sea  and  Gulf  of  Mexico  (stations  2754,  2144,

296  REPORT    OF   NATIONAL   MUSEUM,  1897. 

SPIROLOCULINA  ROBUSTA  Brady. 
( Plate  42,  fig.  1.) 

Much  compressed  laterally,  broad  oval  to  nearly  round,  more  or  less 
concave  on  both  sides;  extremities  angular  or  pointed;  periphery 
rounded,  with  sharp,  projecting  marginal  angles,  which  are  often 
toothed.  Four  to  six  segments  visible  on  both  sides,  outlined  by  the 
acute  prominent  marginal  angles;  aperture  round,  with  a  j-shaped  val- 
vular tooth  in  the  protruding  end  of  the  final  segment.  Longitudinal 
and  transverse  sections  show  the  arrangement  of  chambers  character- 
istic of  the  genus. 

Locality.— Gulf  of  Mexico  (stations  2383,  2309),  200  to  1,200  fathoms. 

SPIROLOCULINA  ROBUSTA,  series. 
(Plate  42,  fig.  2.) 

This  is  a  series,  selected  from  material  dredged  at  a  single  station,  to 
show  an  apparent  evolution  of  Spiroloculina  robusta  from  Biloculina 
depressa.  The  specimens  are  shown  in  pairs,  the  first  of  the  pair  being 
a  whole  shell  resting  upon  its  side,  the  other  being  a  transverse  section 
of  a  similar  shell  standing  on  end.  The  few  specimens  exhibited  show 
a  passage  from  one  form  to  the  other  by  well-defined  steps,  but  with  a 
large  number  of  specimens  the  gradation  is  so  easy  that  it  becomes 
indefinable.  The  series  illustrates  the  difficulties  of  classification  in 
this  order  of  animals. 

Locality.— Gulf  of  Mexico  (station  2377),  210  fathoms. 

SPIROLOCULINA  EXCAVATA  d'Orbigny.

(Plate  48,  fig.  4.) 

This  species  includes  a  wide  variety  of  forms  presenting  all  the  inter- 
mediate stages  from  thick,  slightly  compressed,  nautiloid  shells,  to  the 
long,  cylindrical,  crosier- shaped  varieties,  and  from  these  to  the  thin, 
compressed,  rapidly  widening  forms.  In  all  varieties  the  chambers 
are  without  divisions  or  constrictions,  the  apertures  are  porous,  and 
the  surface,  with  few  exceptions,  is  striate.

(Plate  49,  fig.  1.) 

In  this  variety  the  final  chambers  completely  surround  the  primary 
convolutions,  forming  a  circular,  thin  disk  resembling  the  discoidal 
forms  of  Orbulina,  but  distinguished  by  the  entire  absence  of  septa  in 
the  individual  chambers. 

Locality. — Key  West  Harbor;  shallow  water. 

Genus   ORBICULINA. 

Chambers  subdivided  by  transverse  secondary  septa;  early  segments 
embracing;  arrangement  either  planospiral  throughout  or  partly  cycli-

(Plate  50,  fig.  1.) 

The  only  species  of  the  genus.  A  planospiral,  porcellanous,  imper- 
forate,  polished  shell,  varying  in  contour  from  crosier -shaped  to  dis- 
coidal; surface  usually  pitted  with  minute  depressions;  the  early 
convolutions  embracing;  chambers  narrow  and  regularly  subdivided; 
apertures  a  series  of  pores  in  two  or  more  rows  on  the  outer  edge  of 
the  final  chamber.  It  is  distinguished  from  Peneroplis  by  the  divided 
chambers,  and  from  Orbitolites  by  the  embracing  early  convolutions. 

Localities. — Key  West  and  St.  Thomas;  shallow  water. 

Genus    ORBITOLITES. 

Test  discoidal ;  either  spiral  (non-embracing)  at  the  commencement,

ORBITOLITES    DUPLEX    Carpenter. 
(Plate  51,  figs,  2,3.) 

Shell  thin,  discoidal,  slightly  biconcave;  primordial  chamber  con- 
spicuous, globular;  second  chamber  nearly  surrounds  the  first;  succeed- 
ing segments  rapidly  lengthen  and  quickly  become  annular.  Cham- 
bers divided  by  septa  into  chamberlets,  arranged  in  a  double  tier,  with 
free  communication.  Peripheral  orifices  in  two  rows,  corresponding  to 
the  double  tier  of  chamberlets.  This  latter  feature  together  with  the^ 
early  annular  segments,  distinguish  this  species  from  others  of  the 
genus.  Diameter,  1  to  2.5  mm.  (£.  to  ^-inch). 

Locality.  —  Key  West,  Florida. 

ORBITOLITES    TENUISSIMA    Carpenter. 

(Plate  52.) 

An  extremely  thin  and  delicate  shell,  having  the  form  of  a  circular 
disk  with  flat  surfaces.  In  the  arrangement  of  the  chambers  it  com- 
mences as  a  convoluted,  planospiral,  nonseptate  tube;  it  continues  with 
a  short  series  of  spiral  chambers  and  ends  with  a  broad  series  of  annu- 
lar chambers.  The  spiral  and  annular  chambers  are  partially  divided, 
by  partitions  projecting  from  the  inner  walls,  into  numerous  chamber- 
lets.  The  chamberlets  of  each  annulus  communicate  not  only  with 
each  other  but  also  with  those  of  the  succeeding  annulus.  A  single 
row  of  pores  opens  on  the  margin  of  the  final  chamber.  Diameter,  from 
1  to  20  mm.  (^  to  f  inch).  The  shaded  portions  in  the  figure  are  those 
parts  of  the  specimen  still  occupied  by  the  protoplasmic  substance  of 
the  animal.
